One of the popular ways to use smartphones in public places without disturbing others is to use them with earphones. Earphones are used by people of all ages for listening to music, watching sports/television programs, or even talking to someone over the phone. These devices can be generally classified into two types based on their driver unit, dynamic and BA (Balanced Armature). Dynamic type earphones perform relatively poor in withholding all the sound, letting some sound leak out. On the other hand, BA type earphones fit snuggly into the ears and prevent sound leak. Simultaneously, the users are being blocked out from outside noise. This paper will investigate the volume imbalance between the left and the right BA earphones using a coupler, and how users perceive the volume levels differently. The difference in voltage between the left and the right ones was significant, having 0.8mV with 43.9mV on the left and 44.7mV on the right to form 94dBSPL. This imbalance may cause noise induced deafness when continuously using earphones.

This paper provides a Distributed Morphology (DM) analysis for Hindi nominal (noun and adjectival) inflection. Contra Singh & Sarma (2010), I argue that nominal suffixes contain two morphemes – a basic morpheme, and a restrictedly distributed additional morpheme. The presence of two different morphemes is especially evident when one compares noun and adjectival inflectional suffixes, which Singh & Sarma (2010) do not, since they only look at noun inflection.  I also show that the so-called adjectival inflectional suffixes are not limited to adjectives, and may occur on nouns, provided the noun is not at the right edge of the noun phrase. On the other hand, the regular noun inflection is only limited to nouns at the right edge of the noun phrase. This is demonstrated using a type of coordinative compound found in Hindi. Then, I take the fact that nouns can take either the regular noun inflection or the so-called “adjectival” inflection as motivation for a unified analysis for both sets of suffixes. I demonstrate that after undoing certain phonological rules, the difference between the “adjectival” and regular noun inflectional suffixes can be summarized by saying that the additional morpheme only surfaces in the regular noun inflectional suffixes. Finally, I provide vocabulary entries and morphological operations that can capture the facts about the distribution of the various basic and additional morphemes.

A utopia do direito à cidade,  no  caso específico do Rio de Janeiro, começa, obrigatoriamente, pela  superação da visão dicotômica favela-cidade. Para isso, é preciso que os moradores da favela possam sentir-se tão cidadãos quanto os que têm moradias fora das favelas. A utopia do direito à cidade tem de levar a favela a própria utopia da cidade. Uma cidade que não se fragmente em oposições asfalto-favela, norte-sul, praia-subúrbio e onde todos tenham direito ao(s) seu(s) centro(s). Oposições que expressam muito mais do que diferenças de  localização e que  se apresentam recheadas de  segregação, estereótipos e  ideologias. Por outro  lado, o direito a cidade, como possibilidade histórica, não pode ser pensado exclusivamente a partir da  favela. Mas as populações  que aí habitam guardam uma contribuição inestimável para  a  construção prática  desse direito. Isso porque,  das  experiências vividas, emergem aprendizados e frutificam esperanças e soluções. Para que a favela seja pólo de um desejo que impulsione a busca do direito a cidade, é necessário que ela  se  pense como  parte da história da própria cidade  e sua transformação  em metrópole.Abstract The right  to the city's  utopy  specifically  in Rio de Janeiro, begins by surpassing  the dichotomy approach between favela and the city. For this purpose, it is necessary, for the favela dwellers, the feeling of citizens as well as those with home outside the favelas. The right to the city's utopy must bring to the favela  the utopy to the city in itself- a non-fragmented city in terms of oppositions like "asphalt"-favela, north-south, beach-suburb and where everybody has right to their center(s). These oppositions express much more the differences of location and present  themselves full of segregation, stereotypes and ideologies. On  the other  hand, the right to  the city, as historical possibility, can not be thought  just from the favela. People that live there have a contribution for a practical construction of this right.

Purpose The demand for Saudi Arabian real (SAR) is very high in the pilgrimage (hajj) season while the authority, unfortunately, does not hedge the hajj funds. As such, the hajj funds are potentially exposed to exchange rate risk, which can impact the value of hajj funds and generate extra cost to the pilgrims. The purpose of this paper is to conduct simulations of Islamic hedging for pilgrimage funds to: mitigate and minimize exchange rate risk, identify and recommend the ideal time, amount and tenors of Islamic hedging for hajj funds, estimate cost saving by pursuing Islamic hedging and propose technical and general recommendations for the authority. Design/methodology/approach Forward transaction mechanism is adopted to compute Islamic forward between SAR and Rupiah (Indonesian currency) or IDR. Findings – based on simulations, the paper finds that: the longer the Islamic hedging tenors, the better is the result of Islamic hedging, the decreasing of IDR/USD is the right time to hedge the hajj funds and, on the other hand, the IDR/SAR appreciation is not the right time to hedge the hajj funds. Findings Based on simulations, the paper finds that: the longer the Islamic hedging tenors, the better is the result of Islamic hedging, the decreasing of IDR/USD is the right time to hedge the hajj funds and, on the other hand, the IDR/SAR appreciation is not the right time to hedge the hajj funds. Research limitations/implications The research suggests the authority to (and not to) hedge the hajj fund, depending on economic conditions and market indicators. Even though the assessment is for the Indonesian case, other countries maintaining hajj funds might also learn from this paper. Originality/value To the best of author’s knowledge, this is the first paper in Indonesia that attempts to simulate the optimal hedging of hajj funds.

William of Orange tried to be as absolute as possible. Inroads upon the power of the executive were fiercely resisted: indeed, William succeeded in keeping even the judiciary in a precarious state of independence. To maintain the prerogative and gain the needed supplies from parliament, he relied upon a mixed whig-tory ministry to direct court efforts. Following the Glorious Revolution, the whigs had divided into two principle groups. One faction led by Robert Harley and Paul Foley became the standard-bearers of the broadly based Country party, maintained the “old whig” traditions, did not seek office during William's reign, tried to hold the line on supply, and led the drive to limit the prerogative. The “junto,” “court,” or “new” whigs, on the other hand, were led by ministers who, while in opposition during the Exclusion crisis, held court office, aggressively sought greater offices, and wished to replace monarchy with oligarchy. They soon joined tory courtiers in opposing many of the Country party attempts to place additional restrictions upon the executive. To defend the prerogative and gain passage for bills of supply, William also developed techniques employed by Charles II. By expanding the concept and power of the Court party, he sought to bring together the executive and legislative branches of government through a large cadre of crown office-holders (placemen) who sat, voted, and directed the votes of others on behalf of the government when matters of importance arose in the Commons. So too, William claimed the right to dissolve parliament and call new elections not on a fixed date, as was to become the American practice, but at the time deemed most propitious over first a three-year and then (after 1716) a seven year period.

Abstract Karl Barth’s and Jean-Luc Marion’s theories of revelation, though prominent and popular, are often criticized by both theologians and philosophers for effacing the human subject’s epistemic integrity. I argue here that, in fact, both Barth and Marion appeal to revelation in an attempt to respond to a tendency within philosophy to coerce thought. Philosophy, when it claims to be able to access a universal, absolute truth within history, degenerates into ideology. By making conceptually possible some ‚evental’ phenomena that always evade a priori epistemic conditions, Barth’s and Marion’s theories of revelation relativize all philosophical knowledge, rendering any ideological claim to absolute truth impossible. The difference between their two theories, then, lies in how they understand the relationship between philosophy and theology. For Barth, philosophy’s attempts to make itself absolute is a produce of sinful human vanity; its corrective is thus an authentic revealed theology, which Barth articulates in Christian, dogmatic terms. Marion, on the other hand, equipped with Heidegger’s critique of ontotheology, highlights one specific kind of philosophizing—metaphysics—as generative of ideology. To counter metaphysics, Marion draws heavily on Barth’s account of revelation but secularizes it, reinterpreting the ‚event’ as the saturated phenomenon. Revelation’s unpredictability is thus preserved within Marion’s philosophy, but is no longer restricted to the appearing of God. Both understandings of revelation achieve the same epistemological result, however. Reality can never be rendered transparent to thought; within history, all truth is provisional. A concept of revelation drawn originally from Christian theology thus, counterintuitively, is what secures philosophy’s right to challenge and critique the pre-given, a hermeneutic freedom I suggest is the meaning of sola scriptura.

The subjects were presented with active and passive sentences. For each sentence, they had to choose between two alternative implications. The pattern of choices indicates that in the passive the logical subject was interpreted by the subjects as the focal point of the information asserted by the sentence and as the carrier of overall responsibility for the sentential proposition. In contrast to the passive, there was no clear pattern of preferences for the active. The difference between the two voices was attributed to their markedness asymmetry, the passive being marked and the active unmarked. It is concluded that the active offers a neutral structure for conveying information; a structure available for use when one does not want to superimpose on the information content any stylistic or connotational implications. The passive, on the other hand, suggests special connotations in addition to the basic message.

Climatologists have recently introduced a distinction between projections as scenario-based model results on the one hand and predictions on the other hand. The interpretation and usage of both terms is, however, not univocal. It is stated that the ambiguities of the interpretations may cause problems in the communication of climate science within the scientific community and to the public realm. This paper suggests an account of scenarios as props in games of make-belive. With this account, we explain the difference between projections that should be make-believed and other model results that should be believed.

Abstract The concept of a Grotian moment remains rather obscure in international law. On the one hand, it can refer simply to an empirical fact which galvanises the ordinary law-making processes, whether treaty-making or State practice, resulting in major shifts in international law. On the other hand, a Grotian moment might be seen as an event so significant that it results in an extraordinary shift in international law without full adherence to the processes for law-making. The former understanding has little legal significance, while the latter, which would be legally significant, would be controversial and without legal basis. Against this background the article discusses the intersections between peremptory norms and Grotian Moments. It does this by looking at the intersection between the two concepts as well as the intersection between Grotian Moments, on the one hand and, on the other hand, particular jus cogens norms. With respect to the former, for example, the article will consider whether the high threshold of peremptory status facilitates and hinders Grotian moments. With respect to the latter, the article will consider particular norms that have been said to have shifted on account of the Grotian moments, namely the right to use of force in self-defence as well humanitarian intervention.

"The fundamental transformations through the Romanian state passed since the Revolution of December 1989, have also put their mark on the legal system. For this reason, there have been major changes in the content of administrative law. However, the regulation of the territorial-administrative subdivisions survived the change of political regime, due to Law 2/1968. Moreover, regulations on administrative-territorial subdivisions are also found in Law 215/2001 and in the 1991 Constitution, revised in 2003. This has led to problems of interpretation. Thus, on the one hand, we need to identify who has the right to constitute administrative-territorial subdivisions, and on the other hand, it must be seen whether the answer to the first question, leads to a possible interpretation that would be unconstitutional. At the same time, administrative-territorial subdivisions have created problems of interpretation regarding their legal capacity. Through this article, we have proposed to look at the issues mentioned above."

The purpose of this study was to investigate the prevalence of playing-related musculoskeletal disorders (PRMDs) among Japanese female classical pianists of different age groups. The causal factors for PRMDs also were examined. A group of 203 senior pianists, including piano teachers and students with piano majors at high schools and colleges, were surveyed using questionnaires. Results showed that 77% of these pianists suffered from PRMDs in at least one of their body portions. This value was larger than those reported in Western countries. Forty-four percent of these were serious enough to warrant medical treatment, which was a lower rate than reported in Western countries. The difference in these numbers may reflect the current state of understanding of PRMDs among Japanese pianists and their educators. The prevalence of PRMDs was found to be age-dependent. In the student groups, the finger/hand had the highest rate of PRMDs, followed by the forearm and shoulder. The senior group, on the other hand, had the highest PRMD incidence at the neck/trunk, followed by the forearm and hand/finger. Care may need to be exercised for these differences. The results also indicated that prolonged daily practice (>4 hours), playing chords forcefully, eagerness about practice, and nervous traits were found to contribute to the development of PRMDs in these pianists. Hand size was, on the other hand, not a significant risk factor of PRMDs.
